Ah yes, it is even in TFM... I should R it more... (sync seems to be fine
for non-rv10 files)

Hypothetical example of how the -vop commandline may look in the above
case. Assume the movie is 640x288 and output is two tv's, one at
/dev/video0 (left) and the other at /dev/video1 (right).

mplayer -vop vo=zr:/dev/video0,crop=320:288:0:0,{vo=zr:/dev/video1,\
crop=320:288:320:0}=split movie.avi

(it looks a bit weird in right-to-left mode) It reproduces mpi's (without
memcopy of course) and sends the reproduced one through the chain between
the { }. The 'original' mpi's are sent through the part of the chain after
the {. (after as in 'right to left'). vo specific options should be in the
'subdevice', in this case, to make clear for which device they are meant.

I have no incentive to put the jpeg encoder in libavcodec. I want to have
enough freedom to implement paralel encoding for interlaced output (do the
color planes once (25% gain), this means using 2 bitwriters and two
buffers) and I find this stuff too specific to try to fit it in the
libavcodec achitecture.

Greetings,

Rik.
